CarPlay Disconnecting - iPhone XS Max

Dear all wise and all knowing Apple Community 🙂

I recently switched from my iPhone 7+ running iOS 12.0 to an iPhone XS Max running iOS 12.0.

I have a 2018 Audi S4 with the latest firmware from Audi.

With the switch to the XS Max, seems that my Apple CarPlay will get into a cycle of disconnecting and reconnecting

every 30 seconds or so.

I tried reverting back to my 7+ and works fine.

1. Siri is enabled.

2. The USB Lockout is turned off on the XS Max. The 7+ had the lockout turned on

but made no difference in the XS Max toggling on or off.

3. Swapped the cables to the one in the box of the iPhone XS Max and USB ports

in the car. This had no impact on the XS Max recycling the connection. The 7+ is uneffected

business as usual.

Not sure if this is tied in with the authentication issue with the charger. I go over wired carplay and the 30

second increment is suspect as that is my lockout time on the phone.

Curious if others are facing this.

Thanks!

I have the same issue with CarPlay disconnecting in my 2018 Audi A4 Allroad. I have been visiting my Audi workshop aswell for some troubleshooting with no luck. They could only refere to miss match between iOS version and Audi MMI versions and advices me to wait for upcoming updates...if any...

I did a quick try of the above mentioned tip with flight mode but it didn’t work for me. I will try again...

One more thing, for information, is that I also have the Audi phone box with wireless charging of my iPhone 8 but when connected to CarPlay USB port but it still keeps disconnecting (regardless of wireless charging or not). It is getting very frustrated, since it is a neat function that only should work...

I’ve tried my phone in a Volkswagen Passat CarPlay system and it works flawless, makes me wonder if it is an Audi problem still?

Read everyone’s replies- I am having this same issues with my Max, but I have a BMW X1. Mine does not connect at all but says CarPlay is not supported, when it worked perfectly fine with my old iPhone 7!

Apple needs to fix this!

2018 Q5. iPhone XS. Same issue. I get a max of 30-60 seconds of connectivity then the MMI tells me I have no compatible device plugged in. My phone is on the latest iOS (as of this date 12.1). Another thing I noticed is that when I switch the MMI to Media, there is a message on the screen about there being an issue with the power on my device. Disconnecting the cable and reconnecting gives me another 30-60 seconds then poof.. Same thing. Sad, one of the nicer features the car has with CarPlay and Waze on the phone.. Works GREAT! for 30-60 seconds. Hope this gets corrected soon. I also came from an iPhone 7 that worked perfectly.

I can also confirm, not every usb meter work. Purchased one from my local computer dealer but with this type plugged in my A4 allroad 2018 USB port, CarPlay doesn’t even start up. Phone will just charge...

Tried the tip with flight mode more thoroughly as well, with no luck. Keeps disconnecting CarPlay...

I will go and order the usb meter from amazon today. Hope it works until apple (or Audi) can solve this issue.

I have the iPhone 8, running on iOS 12.1.

Same problem. 2018 Audi A5 Sportback. Switched from an iPhone X to XS Max. Running latest OS 12.1 cuts in and out. Old phone is fine, no issues. Just Carplay though the phone remains charging for the entire time.

I can confirm after updating my xs max to ios 12.1.1 that the issue hasn’t been solved yet. After almost 2 months with the Xs, this is ruining my experience. What such an annoying issue!

Ford Taurus

Ford Edge

Ford Mustang

Ford Escape

Dodge Challenger

Chevrolet Malibu

Chevrolet Cruze

Have been having the same Car Play issue with 2018 Audi Q7 since switching to new XS Max (12.1.2) from iPhone X. Tried all resets, car and phone, no luck. Never had an issue with the Q7 and my iPhone X for almost a year. Now, the iPhone disconnects every 5 minutes, rarely connects unless I unlock it first. Very frustrating, and dangerous.

Same issue with 2018 Audi SQ5.

Tried all trouble shooting as described above. No success.

Sometimes I can go hours with a perfect connection. Othertimes the phone will connect and reconnect over 20 times in a 10 minute period.

I also drive a 2018 Volvo XC60 and 2018 Ford F-150 and haven’t encountered this same issue.

12 Pages of Carplay Disconnects - various models and always the same issues!

I tried everything already - even bought several different models of usb-meters.

No permanent success!

Apple - you really need to fix this asap.

@allen134

I don't understand why should a Y-Splitter make any difference? Does it have power-management capability?

Others mentioned USB-Meters fixed their problems - I ordered 4 different Meters - no success!

Jeep Grand Cherokee Summit and iPhone XS MAX

Confirmed my Uconnect is latest version so upgrade available on the car side.

Same issue. Totally regret upgrading from my iPhone X which was stable with CarPlay. Too bad I traded it in for the XS MAX so now I am stuck as I cannot go back.

Apple, this is a brand new yet defective phone what can we do ?

Jan 9, 2019 6:42 AM in response to ravilach

Same! I'm so frustrated. I have an Audi 2018 Q5, it cuts off and on during maps and text and everything else. Never had the issue with my iphone 7. I don't see any response for fixes. Apple please help us!

I had my car in for service yesterday and service is certainly aware of the issue. As we've determined its on Apple's end to fix, so wondering if anyone is on the beta program and can confirm if iOS 12.1.3 beta 4 has addressed the issue?

Jan 10, 2019 6:29 PM in response to QandnotU

Tried entering a bug report on the Apple site to try and get their attention but the submit button was greyed out LOL

Guess they do not want to hear about it !!
